Application filed September 30, 1891. $eria1No. 407,275. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR J. MOXHAM, of J ohnstown, in the county ofOambria and State of Pennsylvania, have invented a new and usefulRailroad-Rail Chair, which invention is fully set forth and illustratedin the following specification and accompanying drawings.

The object of this invention is to provide a chair for a railroad-railof channel form which, in addition to its peculiar form, shall offer noobstruction to the laying of ordinary streetpavement with broken joints.

The invention will first be described in detail, and then particularlyset forth in the claims.

In the accompanying drawings, Figure 1 shows the chair in cross-section,having a rail of ordinary channel form secured thereto. Fig. 2 is a sideelevation showing the chair uniting the ends of two contiguous rails.Fig. 3 is a side elevation of Fig. 1, looking to the left. Fig. iis aside elevation on a smaller scale, showing the joint-chair shown in Fig.2 uniting two contiguous rails, and also an intermediate chair, such asshown in Fig. 3.

In the figures the several parts are respectively indicated byreference-letters, as follows:

The letter It indicates a rail of ordinary channel form provided withexterior lugs '1" on the bottoms of its vertical webs s. The letter 0indicates a chair for said rail of hollow or box form, having on eachside a protrusion or oifset F. Said chair is preferably shaped to fitunder the head of the rail, as shown.

The letters H H indicate two clamps, one on each side, offset as shownat G G, to fit over and clamp the lugs r on the rail and the offset F onthe chair. A bolt 1) is passed through the clamps H and the sides of thechair and is secured by means of a nut 12, and thus all the parts arefirmly secured together. Said bolt is passed through the recesses formedin the clamps H H, between the offsets or bear ings G G, and its headand end lying within said recesses form no obstruction to thestreetpaving. A flat plate of metal W is inserted in the chair to act asa stiffener, said plate being seated in the recesses formed by theoffsets or protrusions F F.

The letter 0 indicates strengthening-braces, which may, if desired, bestamped out on each side at the angle formed between the side of thechair and its foot.

When the chair is to be used as a jointchair uniting the ends of twocontiguous rails, as shown in Fig. 2,it is made of greater length, andfour bolts 12 may be used, as shown in said figure, the letter Jindicating the contiguous ends of the two rails.

Having thus fully described my said invention, I claim 1. Thecombination, with a rail of channel form provided with lugs on itsvertical webs, of an interior chair having projections, as F, and twoexterior clamps offset to fit over said lugs and projections above andbelow the same, each of said clamps having a recess adapted to receiveeither the head or nut of a fastening-bolt.

2. The combination of a rail of channel form provided with lugs on itsvertical webs, an interior chair having projections, as F, two exteriorclamps offset to fit over saidlugs and projections, and a bolt passingthrough said clamps and chair and having its head and nut seated inrecesses formed in said clamps between said lugs and projections.

3, A rail-chair of box form provided with an inserted horizontalstiffening-plate.

4. In combination with a rail-chair of box form having recesses in itssides, a horizontal stiffening-plate, as W, inserted in said reoesses.
